Mathematical Mysteries of the Periodic Table previous

There is much more to say. But not tonight!



The Road goes ever on and on
Out from the door where it began.
Now far ahead the Road has gone,
Let others follow it who can!
Let them a journey new begin,
But I at last with weary feet
Will turn towards the lighted inn,
My evening-rest and sleep to meet.

— J. R. R. Tolkien
